Title: Tyre tread pattern
Inventor: POQUE DIONYSIUS
IPC: B60C11/00
Filed: 1991-03-07
Abstract: A pneumatic vehicle tyre has tread surface profile elements 41 to 417 which have grooves of different lengths. These grooves may be combined with fine grooves (9) (Figs 4, 5, 7). As a result of such grooves being distributed irregularly, the vibration frequencies of the profile elements are split into a broad frequency spectrum, so that the noise level produced by the tyre is substantially reduced. The profile elements may be at angles of 45 DEG  to 90 DEG  with respect to the central plane of the tyre. <IMAGE>

Title: Tracking apparatus
Inventor: JEONG TAE-HWA
IPC: G05D3/12
Filed: 1992-09-25
Abstract: Digitized video signals, representing the same region of the field of view of a camera (5) at different times, are stored in first and second buffers (70, 80). Corresponding bits in the buffers (70, 80) are exclusive-ORed by an exclusive OR gate (90) and the resultant parallel signal converted into a serial signal by a parallel-to-serial converter (100). Portions of the serial signal corresponding to the object data in the first and second buffers (70, 80) are determined by integrating the serial signal and forming it into a rectangular waveform, each pulse of the waveform representing the position of the object at said different times. The period between the rising edges of pairs of pulses is determined to produce a signal, representing the degree of movement of the object, which is then used to control a motor (170) to redirect the camera (5) to track the object. <IMAGE>
